摘　　要：叠后地震数据对页岩非均质性不敏感,应用叠前反演获得弹性参数极为必要。页岩可压裂性主要与石英含量有关,杨氏模量和泊松比是2个重要的参数,综合应用地震、地质、测井、微地震等信息是页岩油气"甜点"预测成功的关键。Poststack seismic data is not sensentive to heterogeneity of shale,so it is very important to get elastic parameters by prestack data inversion. The fracturbility of shale is mainly associated with quartz,and Young＇s module and Poisson ratio are two important parameters,on the other hand,Lam＇s coofficents can be used,too. Integration of seismic,geology,well- logging and micor- seismic information is vital for ＂sweet spot＂prediction.
